Product Description
solid composite halogen-free phosphorus-nitrogen containing intumescent flame retardant
Product description:
TF-PU501 is solid composite halogen-free phosphorus-nitrogen containing intumescent flame retardant, it acts both in the condensed
phase and the gas phase.
Technical Data Sheet / Specification :
| Specification | TF-PU501 |
| Appearance | Gray powder |
| P2O5 content (w/w) | ≥41% |
| N content (w/w) | ≥6.5% |
| pH value (10% aqueous suspension, at 25ºC) | 6.5-7.5 |
| Moisture (w/w) | ≤0.5% |
Characteristics :
1. Gray powder, expands when heated, efficient in smoke suppression.
2. Excellent water resistance, not easy to precipitate, high flame retardant efficiency.
3. Halogen-free and none heavy metal ions. pH value is neutral, safe and stable during production and use, good compatibleness, not to react with other flame retardant and auxiliary.
Application: TF-PU501 can be used solely in flameproof treatment or used together with TEP for rigid polyurethane foam. When singly added 9%, it can reach OI request of UL94 V-0 . When singly added 15%,
it can achieve classification B1 for burning behavior of building materials with GB / T 8624-2012.
What's more , the smoke density of foam is less than 100.
Packing : 25kg/bag, 22mt/20’fcl without pallets, 18mt/20’fcl with pallets. Other packing as request.
Storage: in dry and cool place, keeping out of moisture and sunshine, min. shelf life one year.
